A Feedrate Planning Method for the NURBS Curve in CNC Machining Based on the Critical Constraint Curve

A Feedrate Planning Method for the NURBS Curve in CNC Machining Based on the Critical Constraint Curve

The curvature of the NURBS curve varies along its trajectory, therefore, the commonly used feedrate-planning method, which based on the acceleration/deceleration (Acc/Dec) model, is difficult to be directly applied in CNC machining of a NURBS curve. To address this problem, a feedrate-planning metho...
